Short Tube Newtonian Reflector Telescope. Of course, the 6" f/4 Newtonian Astrograph can also be used for spectacular visual observations of deep-sky and solar system based celestial objects. An included 2". The C8N Optical Tube. The Celestron C8-N Newtonian VX GOTO Telescope uses the “C8N” optical tube, a generic 8” (203mm) f/5 Newtonian reflector with a focal.

A Short Tube Newtonian Reflector Telescope (STNR) is a type of reflecting telescope that uses a combination of curved mirrors to capture and reflect light. This type of telescope is typically smaller and less expensive than other types of reflecting telescopes, making it a popular choice for amateur astronomers.

The basic design of a STNR consists of a main mirror, known as the objective, and a smaller mirror, known as the secondary, mounted at a 45-degree angle to the primary mirror. The primary mirror is curved to focus the incoming light onto the secondary mirror. The secondary mirror then reflects the light back through an eyepiece at the rear of the telescope.

The size of the primary mirror is what determines the amount of light the telescope can capture and the magnification it can provide. The larger the primary mirror, the more light can be gathered and the more powerful the telescope becomes. However, larger mirrors can also be more expensive and may require a larger telescope tube.

A STNR also has a few advantages over other types of reflecting telescopes. One of these advantages is that it is relatively easy to build. The components for the telescope can be purchased separately and then assembled by the user, making it a good choice for amateur builders. Another advantage is that the STNR is usually much lighter and more compact than other types of reflecting telescopes, making it easier to transport and set up.

Uses for a STNR

The primary use of a STNR is for astronomical observation. The telescope can be used to observe planets, stars, nebulae, galaxies, and other celestial objects. It can also be used to observe the moon and other bodies in our Solar System.

In addition to astronomical observation, a STNR can also be used to take photographs of celestial objects. By attaching a digital camera to the telescope, users can capture high-quality images of astronomical objects.

Finally, a STNR can also be used to do some science experiments. Amateur astronomers can use the telescope to measure the brightness of a star, or to track the movement of a planet or asteroid.

Overall, a STNR is an excellent telescope for amateur astronomers who are looking for a cost-effective and easy-to-build telescope. The telescope is lightweight, compact, and can be used for a variety of purposes, making it a great choice for those who want to get into the hobby of astronomy.

How To Collimate Short-Tube (6) Newtonian Reflector Telescopes

Focal lengths are also relatively short when compared to reflector designs making refractors an ideal choice for astrophotographers in search of a wide-field imaging telescope with. , Short Tube Newtonian Reflector Telescope.


Having received helpful feedback from forums and friends over the years, I felt it was time to give back to the online community to assist with making decisions when it comes to metal tubes. Furthermore, it is going to eliminate you from losing valuable time and cash - it’s the real reason I created this site - to help others make a promising choice.
